Do I have to uninstall 1Password7 for 1Password8 to work?

I just installed 1p8 while having the 1p7 installed. I was hesitant to install it since I know apps can be duplicated. so far after I have installed the 1p8 there has been no issue of 1p app duplication. i also saw my other vaults were there. i have a paid teams account as well.

I just needed to delete the old 1p7 zip file that i apparently forgot to clear out in applications. not sure if that part is a glitch.

I'm using also 1p extension on chrome.
